A multimeter is a versatile tool used to measure voltage, current, and resistance in electrical circuits. Calibration ensures accuracy of measurements.

• Multimeters are used to measure voltage, current, and resistance in electrical circuits

• Calibration involves adjusting the multimeter to ensure accurate readings

• Regular calibration is important to maintain the accuracy of the instrument

• Examples of calibration methods incl...read more

To measure current device's other voltages and electromotive force, use a multimeter set to the appropriate range.

• Set the multimeter to the voltage or electromotive force setting depending on what you want to measure.

• Connect the multimeter leads to the appropriate terminals of the device being measured.

• Read the measurement displayed on the multimeter.

• Ensure the multimeter is set to the correct range to avoid damaging t...read more

Time constant of an RC circuit is the time taken for the voltage across the capacitor to reach approximately 63.2% of its final value.

• Time constant (τ) is calculated as the product of resistance (R) and capacitance (C) in the circuit, τ = R * C.

• It represents the rate at which the capacitor charges or discharges in response to a step change in voltage.

• A smaller time constant indicates a faster response of the circuit, w...read more

Comparators are electronic circuits that compare two voltages and output a digital signal based on the comparison. Band pass filter circuit allows only a certain range of frequencies to pass through.

• Comparators are used in applications such as voltage level detection, waveform shaping, and pulse width modulation.

• They have two input terminals for the voltages to be compared and one output terminal for the digital signal...read more

Heat exchangers are devices used to transfer heat between two or more fluids.

• Heat exchangers are commonly used in HVAC systems, refrigeration units, and power plants.

• They work by transferring heat from one fluid to another without the fluids mixing.

• Types of heat exchangers include shell and tube, plate, and finned tube.

• Examples of heat exchangers include radiators in cars and condensers in air conditioning units.
