Product Details
What is a DC resistance tester?
DC resistance tester is a specialized instrument used to measure the resistance value in circuits. It calculates the resistance value by applying a known direct current to the object being measured and measuring the corresponding voltage. According to Ohm's Law, resistance (R) can be calculated using the formula R=V/I, where V is the measured voltage and I is the applied current.
