A heater is specified as 230 V, 10 kW, A.C. What does the 230 V rating represent?

Choose the correct answer

Explanation

In alternating current (A.C.) systems, voltage ratings commonly indicate the root mean square (r.m.s.) value, which corresponds to the effective voltage. Therefore, the 230 V rating refers to the r.m.s. voltage, not the average or peak voltage.
