Title: How do I find the voltage and current of a circuit when given only the resistance? Post by: jthibodeaux00 on Nov 5, 2012 I have a 3V battery powering a circuit where only the resistance is given, in ohms. I need to find the voltage and current of each load of resistors. Any ideas?
Title: How do I find the voltage and current of a circuit when given only the resistance? Post by: Juliakg1 on Nov 5, 2012 Well, you do have the voltage (3V). If the resistors are in parallel then the voltage drop is the same across all the resistors and if the resistors are in series you can first determine the equivalent resistance of the circuit and find the voltage that goes to each one.
parallel Req = R1 + R2 Series 1/Req = 1/R1 + 1/R2 Only other equation you need is V= IR |
