Hey!
I'm a little stumped over this question so I would really appreciate any advice/answers!
i)What is the ammeter reading
ii)What is the resistance for the bulb
iii)What is the power for the bulb and resistor

Hi - it's better to attach picture format files than word docs.
PD across the 10 ohm resistor is 5V
I=V/R
so the current through the 10 ohm resistor is 5/10 Amps
PD across the bulb plus the 5V across the resistor must equal the PD of the battery (6V)
Power is VI - both the bulb and resistor carry the same current because they are in series.
