The current in the kettle heating element is 2500 mA. resistance 480 Ohm. Calculate the tension.

Given:

I = 2500 mA – current in the heating element of the kettle;

R = 480 Ohm – resistance of the electric kettle heating element.

It is required to determine U (Volt) – the voltage of the electrical network.

We translate the units of measurement of the current strength into the SI system:

I = 2500 mA = 2500 * 10-3 = 2500/1000 = 2.5 Amperes.

Then, to determine the voltage of the electrical network, you must use the following formula:

R = U / I, from here we find that:

U = R * I = 480 * 2.5 = 1200 (1.2 kV).

Answer: the voltage across the heating element of the electric kettle is 1200 (1.2 kV).
