Two resistors Ri (12 ohm) and R2 (24 ohm) are parallel across a 6.0 V battery connected in series with negligible internal resistance.
Draw circuit diagram (to the right) and calculate:
1. The total resistance of the two resistors
2. The total current flowing in the circuit
3. The current flowing in Ri
4. The current flowing in R2
5. The total power consumed by Ri and R2
A certain light bulb carries 1.5 amperes of current when connected to a 120 Volt AC circuit. Show calculation. What is its power rating? 240 W, 180 W, 80 W, 100 W
