Question

An electrical appliance has the following parameters: 230 volts, 5 Amperes 1 point
and is used for 2 hours. Calculate the total energy consumed by the
appliance.
O
4.6 kwh
2.3 kwh
2300 kwh
230 kwh​

Answer 1

Answer:

Current Electricity

Explanation:

★ GIVEN ;

» Voltage ( V ) = 230 V

» Current ( I ) = 5 A

» Time ( T ) = 2 hours = 120 min. =

______________________________________________________________________________________

Total Energy Consumed ( H ) = I² R T = V I T

= 230 × 5 × 2 hours

= 1150 × 2

= 2300 Watt / hour

Total energy consumed = 2.3 Kilo watt hour

Option B

Answer 2

Given ,

Potential difference (v) = 230 volt

Current (I) = 5 amp

Time (t) = 2 hr

We know that ,

Energy = (I)²RT

Energy = vIT

Thus ,

Energy = 230 × 5 × 2

Energy = 2300 watt.hour

Energy = 2.3 Kwh

$\sf \therefore \underline{The \: total \: energy \: consumed \: by \: the \: </p><p>appliance \: is \: 2.3 \: Kwh</p><p>}$
