The energy used by an appliance which operates at 240 volts at 15 amp for 4 hr. is A. 0.92 kwhr. B. 3.45 kwhr. C. 14.4 kwhr. D.
Tju [1.3M]

Answer:

C. 14.4 kwhr.

Explanation:

To calculate the energy used by appliance first calculate the power. The formulae for calculating power(<em>P</em>) is P= I \times V, where V stands for voltage and I stands for current.

In the given problem,  V = 240 volts and I = 15 amp. Therefore,

P=240 \times 15 =3600\ watt(w) = 3.6\ kw

Now, formulae for calculating energy used i.e. work(W) is W = P\times t, where <em>t</em> is the time.

In the given question time is 4 hr. Therefore energy used will be,

Energy used (W) = 3.6\times4 =14.4\ kwhr.
