Which electrical parameter is measured in ohms?

• A. Voltage
• B. Power
• C. Current
• D. Resistance

Answer: (D)

Resistance is the electrical parameter measured in ohms. Ohm is the unit of measurement for resistance in a circuit, defined by Ohm's Law, which states that the voltage across a conductor between two points is directly proportional to the current flowing through it, with the resistance being the constant of proportionality. This relationship is expressed as V = IR, where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms. Understanding resistance is crucial for biomedical equipment technicians, as it helps in diagnosing and troubleshooting electrical circuits and devices. For example, knowing the resistance of a component can help determine if it is functioning correctly or if it may be causing issues in the system due to too high or too low resistance. This knowledge is fundamental when working with any electronic or electrical equipment, including those found in healthcare settings.
