3-16-2020 Current and Voltage

Voltage is simply defined as...

• what 'pushes' electrons
• what 'stops' electrons
• moving electrons

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

• increase (speed up)
• decrease (slow down)
• stay the same

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

• 3600 A

• 6.25 A

• 0.16 A

What size resistor would produce a 3 Amp current flow with a 12 Volt battery

• 1 Ohm
• 3 Ohms
• 4 Ohms
• 12 Ohms
