If a circuit has a current of 5 A and a resistance of 10 ohms, what is the voltage across the circuit? (2019)
Step 1: Identify the values given in the problem. We have a current (I) of 5 Amperes (A) and a resistance (R) of 10 Ohms (Ω).
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 5 A and R with 10 Ω. So, it becomes V = 5 A * 10 Ω.
Step 4: Perform the multiplication. Calculate 5 * 10, which equals 50.
Step 5: Write down the result. The voltage (V) across the circuit is 50 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 = I * R.
