Practicing Success
Which of the following statements are correct? A. Two major types of resistors are wire bound resistors and carbon resistors. Choose the correct answer from the options given below: |
A, B and E Only B, C, D and E Only C, D and E Only D and E Only |
A, B and E Only |
Carbon resistors have low temperature coefficient value. Wire wound resistors have a high temperature coefficient value. The magnitude of drift velocity per unit electric field is mobility (m) The internal resistance of dry cells is generally higher than the common electrolytic cells. in case of electrolyte there are no electrons. The electric current is basically due to flow of ions. The potentiometer has the advantage that it draws no current from be voltage source being measured. As such it is unaffected by the internal resistance of the source. |
