Linear Resistance Meter

An ammeter measures current in a circuit, requiring the circuit to be interrupted in series for measurement. A clamp meter, however, allows for direct measurement of current without breaking the circuit. The clamp meter's structural principle relies on a...

The input capacitor for the phototransistor at the bottom is responsible for feeding the operational amplifier (op-amp). However, the output from the phototransistor consistently remains between ground (GND) and the supply voltage (Vcc). The necessity for an input capacitor...

The circuit consists of dual drive integrated circuits (ICs) utilized in a 10 LED level meter configuration. The schematic features two TLM8101 driver ICs, which can be employed as alternatives. The 10 LED level meter circuit is designed to provide...

One cannot expect high performance from a basic detector-based meter. Its sensitivity is merely sufficient to provide a fundamental understanding of the power output that the transmitter can achieve. The detector-based meter operates on a straightforward principle where it measures...

The MOSFET input of the CA3140 is ideally suited for use in a high impedance DC voltmeter. The range selector is controlled by switch S1. The input impedance is limited to 10M by the resistors in the voltage divider,...

The circuit diagram illustrates a high-impedance distribution system characterized by low resistivity distribution. A notable feature is the series resistance of the shunt load current limiting resistor R1, typically valued at five to ten times the internal resistance of...
