Step up transformer have _ turns in secondary coil.
Correct answer: A. More
- A. More
- B. Less
- C. Equal
- D. Zero
Explanation
A Step-Up Transformer is a power distribution transformer in which the secondary currents are higher than its primary voltage. A Step-Up Transformer, therefore "steps up" the voltage supplied. For instance, step-up transformer windings are required to use a 220V device in a country that has a 110V electricity supply. This requires 'more turns' in the secondary coil.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
