Electric Current

filament of a bulb is usually made up of

• nickel

• chromium

• cobalt

• tungsten

Connection of more than one device/ appliance to a single socket is called-

• Overloading

• Short circuit

• Both

Current is...

• moving protons

• moving electrons

• measured in volts

• measured in ohms

If the voltage stays the same, but the resistance goes up, the current will....

• increase (speed up)

• decrease (slow down)

• stay the same

If the current increases it could be because of...

• increasing voltage

• decreasing resistance

• both

This circuit has a 24 volt battery and the resistor is 8 ohms. How many amps are running through the circuit?

• 3 Amps

• 192 Amps

• 2 Amps

• 4 Amps

Resistance is...

• What "slows down" electrons

• What "speeds up" electrons

• Moving electrons

• What "pushes" electrons

When more branches are added to a parallel circuit, ____________________.

• resistance decreases

• voltage increases

• nothing changes

A potential difference of 24 V is applied to a 150 resistor. How much current flows through the resistor?

• 0.15 A

• 3600 A

• 6.25 A

• 0.16 A

This is an example of a _______ circuit

• open

• series

• parallel

• square
