25. 1. What is the current when a 5,000
ohm appliance is connected to a 110
volt line?
26. 2. What current will flow through a coil
having a resistance of 6 ohms if the
voltage is 48 volts?
27. 4. A small light bulb is connected to
a 6 V battery and draws 2 A of
current. What is the net resistance
of the bulb?
28. 5. A motor with an operating resistance
of 32 ¾ is connected to a voltage
source. The current in the circuit is 1.5
A. What is the voltage of the source?
29. Problem #1:
A frying pan is connected to a 110-volt
circuit. If the resistance of the frying pan is
10 ohms, how many amperes does the frying
pan draw?
30. Problem #2:
When a current of 3 amperes is run through
the coiled heating element of a stove, the
resistance of the element is 80 ohms. What
is the voltage of the stove?
31. Problem #3:
A lightbulb carries 0.5 A when 4 volts is
impressed across it. What is the resistance of
the filament in the lightbulb?
