Step 1: (a) Identify the components labelled X_1, Y, R_1 and Z. X_1 is a fuse. Y is a battery. R_1 is a fixed resistor. Z is a rheostat. Final answers for (a): X_1: fuse Y: battery R_1: fixed resistor Z: rheostat X_1: fuse Y: battery R_1: fixed resistor Z: rheostat Step 2: (b) Identify the component labelled v. v is a voltmeter. Final answer for (b): voltmeter voltmeter Step 3: (c) State the unit for R_1. The unit for R_1 (resistance) is . Final answer for (c): ** Step 4: (d) State one use of the component labelled Z. One use of Z (rheostat) is to control/vary the current in the circuit. Final answer for (d): To control the current in the circuit. Step 5: (e) State one use of the component labelled X_1. One use of X_1 (fuse) is to protect the circuit from damage due to excessive current. Final answer for (e): To protect the circuit from excessive current.
