Quiz: Fundamental Science in Maintenance Engineering

Power = Current x Voltage

Power = Current + Voltage

Power = Current / Voltage

Power = Voltage / Current

V = I x R

I = V x R

R = V x I

V = I / R

Flame

Arc

Induction

All of the above

Speed is a scalar quantity, while velocity is a vector quantity.

Speed includes direction, while velocity does not.

Speed is always faster than velocity.

There is no difference.

A uniform field

A field similar to a bar magnet

No magnetic field

A measure of how much a material expands when heated

A measure of how much heat a material can absorb

A measure of electrical resistance

A measure of thermal conductivity

Pressure = Force x Area

Pressure = Force / Area
