3003 LO4 13 RCDs Resistor Values and Test Currents

This is the internals of an RCD. Assume the resistor is 33K Ohms, would the RCD trip if we were using it for normal home use?

• No. There is not enough imbalanced current created.

• Yes. There is enough imbalanced current created.

• No. Not enough current current can flow because the resistor value in Ohms is too small.

• Yes. The resistor has very high resistance in Ohms, so it can trip the RCD by leakage resistance.

• The circuit is balanced, and cannot induce a magnetic field.
