Questions & Step-by-Step Solutions
In a transformer, if the primary coil has 100 turns and the secondary coil has 50 turns, what is the relationship between the primary and secondary voltages?
Step 1: Identify the number of turns in the primary coil (N1) and the secondary coil (N2). Here, N1 = 100 turns and N2 = 50 turns.
Step 2: Write down the formula for the voltage ratio in a transformer, which is V1/V2 = N1/N2.
Step 3: Substitute the values of N1 and N2 into the formula: V1/V2 = 100/50.
Step 4: Simplify the fraction 100/50 to find the ratio: 100/50 = 2.
Step 5: Conclude that the relationship between the primary voltage (V1) and the secondary voltage (V2) is V1 = 2 * V2.
