Ramsay Test Technical Aptitude & Knowledge 3

Question 1

In a simple series circuit with three resistors, how does the current compare at each resistor?

Accepted Answer

It is the same through all three

Answer

In a series circuit the same current flows through every component.

Question 2

Using Ohm's law, what current flows when 12 volts is applied across a 4 ohm resistor?

Accepted Answer

3 amps

Answer

Current equals voltage divided by resistance: 12 / 4 = 3 amps.

Question 3

What is the total resistance of two 10 ohm resistors connected in parallel?

Accepted Answer

5 ohms

Answer

Two equal resistors in parallel give half the value, so 10/2 = 5 ohms.

Question 4

A device that converts electrical energy into rotational mechanical motion is called a:

Accepted Answer

Motor

Answer

An electric motor turns electrical energy into mechanical rotation.

Question 5

A transformer with more turns on the secondary than the primary coil will:

Accepted Answer

Step up the voltage

Answer

More secondary turns than primary raises (steps up) the output voltage.
