Activity 5 Number 2 Letter A only
1. In the circuit shown below, each resistor represents a light bulb. Let R= R2=Ra=R4= 6.000 and ɛ = 12.00v. a) Find the current in each bulb. b) Find the power dissipated in each bulb. Which bulb or bulbs glow the brightest? R1 2. The power rating of a resistor is the maximum power the resistor can safely dissipate without too great a rise in temperature and hence damage to the resistor. R2 R4 3. a) If the power rating of a 15-kW resistor is 5.0 W, what is the maximum allowable potential difference across the terminals of the resistor? b) A 9.0 kn resistor is to be connected across a 120 V potential difference. What power rating is required?
