Question: If a circuit has a total resistance of 10Ω and a current of 5A, what is the voltage across the circuit?
Options:
10V
15V
50V
5V
Correct Answer: 50V
Solution:
Using Ohm\'s Law, V = I * R = 5A * 10Ω = 50V.

Questions & Step-by-Step Solutions
If a circuit has a total resistance of 10Ω and a current of 5A, what is the voltage across the circuit?
Step 1: Identify the values given in the problem. We have a total resistance (R) of 10 ohms (Ω) and a current (I) of 5 amperes (A).
Step 2: Recall Ohm's Law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 5A * 10Ω.
Step 4: Calculate the result: 5 * 10 = 50.
Step 5: Conclude that the voltage across the circuit is 50 volts (V).
Ohm's Law – Ohm's Law states that the voltage (V) across a circuit is equal to the current (I) flowing through it multiplied by the resistance (R) of the circuit.
