If a circuit has a resistance of 5 ohms and a current of 2 A, what is the voltage? (2014)
Step 1: Identify the values given in the problem. We have a resistance (R) of 5 ohms and a current (I) of 2 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 = 2 A × 5 Ω.
Step 4: Calculate the result: 2 A × 5 Ω = 10 V.
Step 5: Conclude that the voltage in the circuit is 10 volts.
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.
