Front

Name examples of metallic engineering materials.

Back

Cast iron, carbon/alloy steels, stainless steel, aluminium, copper, brass, bronze, lead.

Front

What is Ohm's Law?

Back

V = I — R (Voltage = Current — Resistance).

Front

What are basic arithmetic operations used in engineering?

Back

Addition, subtraction, multiplication, division (whole numbers, fractions, decimals).

Front

What are lines of flux in a magnetic field?

Back

Invisible lines showing magnetic force; flow from north to south.

Front

How do you calculate power in a circuit?

Back

Power (W) = Voltage (V) × Current (I).

Front

What are mean, median, and mode?

Back

Mean: average; Median: middle number; Mode: most frequent value.

Front

How is AC current produced?

Back

By rotating a coil in a magnetic field (alternating direction of current).
