Expert Solution
Step 1
4.(a)
Write the expression for the power supplied by the battery.
Step 2
(i)
Calculate the factor at which the power supplied in the circuit changes when voltage is doubled, and the resistance increased by the factor of four.
Therefore, there is no change in the power supplied in the circuit changes when voltage is doubled, and the resistance increased by the factor of four.
