If a circuit has a resistance of 5 ohms and a current of 2 amperes, what is the voltage across the circuit?
Step 1: Identify the values given in the problem. We have a resistance (R) of 5 ohms and a current (I) of 2 amperes.
Step 2: Recall Ohm's Law, which states that Voltage (V) equals Current (I) multiplied by Resistance (R). The formula is V = I * R.
Step 3: Substitute the values into the formula. Replace I with 2 A and R with 5 Ω: V = 2 A * 5 Ω.
Step 4: Perform the multiplication: 2 * 5 = 10.
Step 5: Conclude that the voltage (V) across 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, multiplied by the resistance (R) of the conductor.
