A portable communication transceiver operates at a potential difference of 7.4 V.
The current in the transceiver is 0.65 A.
Calculate the energy transferred to the transceiver in 5 minutes.
Use the equation:
energy transferred=current×potential difference×time in seconds \text{energy transferred} = \text{current} \times \text{potential difference} \times \text{time in seconds} energy transferred=current×potential difference×time in seconds31 exam-style questions on Edexcel GCSE Physics 10.3 Electrical energy and power.
