.

Label all the currents on the given point , and represent current with arrows

.

Complete the same task for circuit below

.

What is the effect of changing width and length of component , on its resistance component

.

.

Determine if the light bulb will de-energize for each of the following breaks in the circuit. Consider just one break at a time:

We have three batteries of 3 volt 3 volt and 1.5 volt. Our device needs to be operated at 4 volt. How can we connect these three batteries , so we get total voltage of 4 volts

.

.

What is the difference between a cell and a battery?

.

.

Following is an example of which connection (seires or parallel)

• Christmas Light strings
• A Chandelier
• A Voltage Divide
• Room Wiring
• Batteries in the remote
• Car head lights
• Street lights

A potentiometer is connected is series with a motor, to control its speed. The potentiometer has a rating of 10 ohm with power rating of 25 watts

When operating the motor at a voltage of 16 volts and a current of 2 amps, though, smoke

begins to pour out of the potentiometer, indicating that its power rating is being exceeded.

The technician is perplexed! According to his calculations, the potentiometer should be

dissipating less than 25 watts of power. Why, then, is a potentiometer rated for 25 watts

burning up under this condition?
