• 

Match the following

• Ohms

• R

• Amps

• E

• Watts

• I

• Volts

• P

Match the following

• Flow

• I

• Pressure

• R

• Works

• P

• Oppose

• E

Answer explanation

P is for Power and Power expresses work performed by the load device.

I is for Amperage, which is the measurement of current flow

E is for Voltage and Voltage is Electrical Pressure.

R is for Resistance, which opposes current

Match the following

• Pressure

• Ohms

• Flow

• Watts

• Oppose

• Volts

• Works

• Amps

Match the following

• E / I

• E =

• I x R

• R =

• I x E

• I =

• E / R

• P =

Match the following

• Amps x Resistance

• P =

• Amps x Pressure

• I =

• Voltage / Resistance

• R =

• Volts / Current

• E =

Tech A says E = I x R. Tech B says E = R x I.

Who's correct?

• Tech A

• Tech B

• Both

• Neither

A circuit with a 12V battery and 2 loads with 2ohms each, Which formula look best when calculating It.

• It = Et / (R1+R2)

• It = (R1+R2) / Et
