The resistance of a galvanometer is $50\ \Omega$. It is converted into a voltmeter or an ammeter. Calculate the resistance of the voltmeter and ammeter to an accuracy of 2sf. Only with the mention below in the subparts.
(i)[1.0]
A voltmeter using a $10\text{ k}\Omega$ resistor is:
- (a)$10050\ \Omega$
- (b)$10.050\text{ k}\Omega$
- (c)$10000\ \Omega$
- (d)$10\text{ k}\Omega$
(ii)[1.0]
An ammeter using a $10\text{ m}\Omega$ resistor is:
- (a)$50\ \Omega$
- (b)$10\text{ m}\Omega$
- (c)$0.0999\ \Omega$
- (d)$50.0999\ \Omega$
