If a circuit has a total resistance of 12Ω and a current of 1.5A flows through it, what is the voltage across the circuit? (2022)
Step 1: Identify the values given in the problem. We have a total resistance (R) of 12 ohms (Ω) and a current (I) of 1.5 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 = 1.5A * 12Ω.
Step 4: Calculate the multiplication: 1.5 * 12 = 18.
Step 5: Conclude that the voltage across the circuit is 18 volts (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 = IR.
