Questions & Step-by-Step Solutions
If a circuit has a current of 0.5 A and a resistance of 20 ohms, what is the voltage?
Step 1: Identify the values given in the problem. We have a current (I) of 0.5 A and a resistance (R) of 20 ohms.
Step 2: Recall Ohm's Law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 0.5 A * 20 Ω.
Step 4: Calculate the result: 0.5 * 20 = 10.
Step 5: Conclude that the voltage (V) 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.
