Heres an example for a circuit with three components A, B, and C. Log in Sign up Terms of Use We use cookies to make wikiHow great. Ralph Childers is a master electrician based in the Portland, Oregon area with over 30 years of conducting and teaching electrical work. Ralph received his B.S. In A Series Circuit The Largest Amount Of Power Is Dissipated By License As WellElectrical Engineering from the University of Louisiana at Lafayette and holds an Oregon Journeyman Electrical License as well as electrician licenses in Louisiana and Texas. The electrical charge leaves the positive terminal of the power supply, passes through each resistor or other components in turn, then returns to the negative terminal. In A Series Circuit The Largest Amount Of Power Is Dissipated By Series Circuits AreThe properties of series circuits are not hard to learn, but it can take some thinking to figure out how to use them. Ohms Law tells you that they are related in a simple way: V IR. If you get stuck at any point and dont have enough information for the steps below, look for a chance to use Ohms Law. For example, if you know the resistance and voltage of a circuit, rearrange V IR to I V R, and plug in the known values to solve for I, the current. If you are trying to solve for the resistance of a single resistor, you will need to know the voltage and current for that resistor. In a series circuit, all of the current passes through every resistor in turn. In A Series Circuit The Largest Amount Of Power Is Dissipated By Full Resistance ToThis means each resistor contributes its full resistance to the circuit. If you know each individual resistance value, just add them together to find the total resistance of the circuit. One resistor R 1 has 3 (ohms) of resistance, and the second resistor R 2 has 6 of resistance. The total resistance of the circuit is equivalent to the sum of the two individual resistances: R t o t a l R 1 R 2 3 6 9 displaystyle RtotalR1R2369. The voltage drop across the total circuit is determined by the voltage source, typically a battery. This is often labeled on your circuit diagram, next to two or more parallel lines of different length. What is the voltage drop across R 2 V t o t a l V 1 V 2 displaystyle VtotalV1V2 9 5 V 2 displaystyle 95V2 V 2 9 5 4 displaystyle V29-54 volts. Electrical charge flows constantly around the circuit, creating the current. A series circuit only has one path for this flow, so the current is the same at all points on the circuit. There are no branches to split the current.) As long as you know the voltage and resistance at any point on the circuit (or for the circuit as a whole), you can use Ohms Law to find the current: I V R. ![]() How much current flows through this circuit You know the values of V and R for the light bulb, so you can use Ohms Law to solve for the current: I 80V 100 0.8 A (amps) Because the current is the same anywhere on a series circuit, the answer is 0.8 amps. Be careful: you cannot use the circuits total voltage drop 220V. Ohms Law only works if you use values for the same portion of the circuit, and this problem does not tell you the total resistance of the circuit. ![]() It may help to fill out a VIR chart as you go, with a separate row for each component and the whole circuit.
