GK Question

technology easy true_false

Ohm's Law states that current through a conductor is directly proportional to voltage and inversely proportional to resistance.

  1. True
  2. False

Answer: True

Ohm's Law: I = V/R, where I=current (Amperes), V=voltage (Volts), R=resistance (Ohms). Fundamental for circuit analysis, component selection, and troubleshooting. Applies to ohmic materials at constant temperature. Non-ohmic devices (diodes, transistors) have non-linear V-I characteristics requiring advanced modeling.
