A filament lamp and a 220 ohm resistor are connected in series to a battery of E.M.F 6.0 V. The battery has no internal resistance. A high resistance voltmeter placed across the resistor measures 1.8 V
(a) Calculate current drawn from the battery
(b) the P.D. across the lamp
(c) total resistance of the circuit
(d) number of electrons passing through the battery in a time of 1 minute
elementary charge is 1.6 x 10^-19
but please can anyone solve the all four parts ?

Answer:
A filament lamp and a 220 ohm resistor are connected in series to a battery of e.m.f. 6.0 V. The battery has negligible internal resistance. A high-resistance voltmeter placed across the resistor measures 1.8 V.
Calculate:
a) the current drawn from the battery
b) the p.d. across the lamp
c) the total resistance of the circuit
d) the number of electrons passing through the battery in a time of 1.0 minute. (The elementary charge is 1.6*10^-19C)
