WAEC - Physics (2020 - No. 19)

A moving-coil galvanometer which gives a full-scale on deflection with 0.005A is converted to a voltmeter reading up to 5V using an external resistance of 975\(\Omega\). What is the resistance of the metre?
0.25\(\Omega\)
2.50\(\Omega\)
25.00\(\Omega\)
250.00\(\Omega\)
