Questions & Step-by-Step Solutions
If a circuit has a total current of 5 A and a total resistance of 10 ohms, what is the voltage across the circuit?
Correct Answer: 50 V
Step 1: Identify the total current in the circuit, which is given as 5 A.
Step 2: Identify the total resistance in the circuit, which is given as 10 ohms.
Step 3: Recall Ohm's law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 4: Substitute the values into the formula: V = 5 A * 10 ohms.
Step 5: Calculate the voltage: V = 50 V.
Ohm's Law – Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it and the resistance (R) of the conductor, expressed as V = I * R.
