4 electrical appliances with equal resistances (10 ohms each) are connected in series in the electrical circuit.

4 electrical appliances with equal resistances (10 ohms each) are connected in series in the electrical circuit. The current in one of them is 1.5 A. What is the total voltage in this circuit?

To find the total voltage of the formed circuit, we will use the formula:

U = R * I = n * R1 * I1.

Variables: n – the number of switched on electrical appliances (n = 4 pcs.); R1 is the resistance of each device (R1 = 10 Ohm); I1 is the current in one of the electrical appliances, the current in the circuit (I1 = 1.5 A).

Calculation: U = n * R1 * I1 = 4 * 10 * 1.5 = 60 V.

Answer: The voltage in the formed circuit is 60 V.
