Example Question #61 : Circuits
What is the current in a circuit with a resistor followed by a resistor that are both in parallel with a resistor? The voltage supplied to the circuit is 5V.
Possible Answers:
Correct answer:
Explanation:
Resistors in serries add according to the formula:
Resistors in parallel add according to the formula:
We can find the total equivalent resistance:
Now we can use Ohm's law to find the current:
Solve:
Example Question #61 : Circuits
A battery supplies power to a circuit with a current of . What is the resistance in this circuit?
Possible Answers:
Correct answer:
Explanation:
To find resistance from voltage and current, we will need to use Ohm's law:
We are given the voltage and current, allowing us to solve for the resistance.
