(a(i))[1]
State the energy change that takes place in the battery.
(a(ii))[1]
State the energy change that takes place in the resistors.
(b(i))[1]
The circuit current is $I$. State the rate of energy transformation in the battery.
(b(ii))[1]
The circuit current is $I$. State the rate of energy transformation in resistor A.
(c)[3]
The resistors are formed from metal wires. The data for the resistors are shown in Fig. 6.2. Use the information in Fig. 6.2 to find the ratio $$\frac{\text{power dissipated in A}}{\text{power dissipated in B}}.$$
(d)[2]
Resistors A and B are connected in parallel across the same battery of e.m.f. $E$. Find the ratio $$\frac{\text{power dissipated in A}}{\text{power dissipated in B}}.$$
