`50 Omega` and `100 Omega` resistors are connected in series. This connection is connected with a battery of 2.4 volts. Whne a voltmeter, then the reading of the voltmeter will be `100 Omega` resistor, then eh reading of the voltmeter will be

Options

A. `1.6 V`
B. `1.0 V`
C. `1.2 V`
D. `2.0 V`

Answer

C

Explanation

(c ) Equivalent resistance of the circuit `R_(eq) = 100 Omega`
current through the circuit `i= (2.4)/(100) A`
`P.D.` across combination of voltmeter and `100 Omega`
resistance `= (2.4)/(100) xx 50 = 1.2 V`
Since the voltmeter and `100 Omega` resistance are in parallel, so the voltmeter reads the same value i.e.,
