Find the magnitude of the resultant of shown forces :-

Options

A. 2A, 200V
B. 1.5A, 100V
C. 2.7A, 220V
D. 2.2 A, 220 V

Answer

D

Explanation

Since `V_(C) = V_(L) = 200 V `
`V = sqrt(V_(R)^(2) + (V_(C) - V_(L))^(2))`
`rArr V = V_(R)` Reading of voltmeter = 220 V
Current `I = (V)/(R) = (220)/(100) = 2.2 A `
