(a)[2]
Calculate the total resistance of the two resistors shown in Fig. 8.1.
(b)[3]
Calculate the current through the resistor.
(c)[1]
State the name of the particles that travel through the metal wires when current flows in the circuit.
(d)[2]
A student uses a meter to measure the potential difference across the $16\,\Omega$ resistor. On Fig. 8.1, draw the electrical symbol for this meter and show how it is connected.
