# How To Solve Parallel Circuit Problems

The current through the circuit depends on the voltage supplied by the voltage source and the resistance of the resistors.For each resistor, a potential drop occurs that is equal to the loss of electric potential energy as a current travels through each resistor.Current (I) is how much physical electricity is running through each wire, which is measured in Amps.

If One result of components connected in a series circuit is that if something happens to one component, it affects all the other components.

For example, if several lamps are connected in series and one bulb burns out, all the other lamps go dark.

In Current and Resistance, we described the term ‘resistance’ and explained the basic design of a resistor.

Basically, a resistor limits the flow of charge in a circuit and is an ohmic device where $$V = IR$$. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the of the circuit.

The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances.

In Figure, the current coming from the voltage source flows through each resistor, so the current through each resistor is the same.For Figure, the sum of the potential drop of each resistor and the voltage supplied by the voltage source should equal zero:$V - V_1 - V_2 - V_3 = 0,$$V = V_1 V_2 V_3,$$= IR_1 IR_2 IR_3,$$I = \frac = \frac.$Since the current through each component is the same, the equality can be simplified to an equivalent resistance, which is just the sum of the resistances of the individual resistors.Any number of resistors can be connected in series.The sum of the individual currents equals the current that flows into the parallel connections.Resistors are said to be in series whenever the current flows through the resistors sequentially.They solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.Z_T =((70 60j)(40-25j))/(110 35j) =((92.20/_40.60^text(o))(47.17/_-32.01^text(o)))/(115.4/_17.65^text(o)) (We do the product on the top first.) =((92.20xx47.17)/_(40.60^text(o)-32.01^text(o)))/(115.4/_17.65^text(o)) =(4349.074/_8.59^text(o))/(115.4/_17.65^text(o)) (Now we do the division.) =(4349.074)/115.4/_(8.59^text(o)-17.65^text(o)) =37.69/_-9.06^text(o) (We convert back to rectangular form.) =37.22-5.93j A 100\ Ω resistor, a 0.0200\ "H" inductor and a 1.20\ mu"F" capacitor are connected in parallel with a circuit made up of a 110\ Ω resistor in series with a 2.40\ mu"F" capacitor.The voltage of a circuit is displayed by the symbol found in Fig. You can simply transcribe this value and keep it until we are solving for current (I) in Step 3. These resistors can be organized in two basic ways, either in parallel or in series. Look at the circuit you are given and identify which type of resistance your circuit uses, then you may proceed to step 2.A Resistor is a small component of a circuit used to change how much resistance is within the circuit. Series resistors look like a “string” on a circuit, each one is placed end-to-end in a row, all traveling in the same direction. To find the total resistance of a series configuration, you simply add them together. Once you have found the total resistance (R) and given voltage (V) we plug it into the Ohm’s Law equation (I=V/R). A battery with a terminal voltage of 9 V is connected to a circuit consisting of four $$20 \, \Omega$$ and one $$10 \, \Omega$$ resistors all in series (Figure).Assume the battery has negligible internal resistance.
