**Explanation:**

The voltage coil of a single-phase house energy meter is typically connected across the supply voltage. Its purpose is to measure the voltage supplied to the load.

**Inductive Nature of Voltage Coil:**
The voltage coil of a house energy meter is highly inductive. This means that it has a significant inductance value. The inductance is provided by a coil of wire wound around a magnetic core. When an alternating current flows through the coil, it induces a magnetic field in the core, which in turn produces a voltage across the coil according to Faraday's law of electromagnetic induction.

**Phase Angle:**
The voltage coil of the energy meter has a phase angle equal to the load power factor angle. The power factor is the ratio of the real power (in watts) to the apparent power (in volt-amperes) in an electrical circuit. It indicates the efficiency of the circuit in converting electrical power into useful work. The power factor angle represents the phase difference between the current and voltage waveforms in an AC circuit.

**Measurement of Voltage:**
The voltage coil measures the voltage supplied to the load by producing a voltage proportional to the supply voltage. This induced voltage is used to drive the rotating disc or other measuring mechanism in the energy meter, which records the energy consumption of the load.

**Conclusion:**
Therefore, the voltage coil of a single-phase house energy meter is highly inductive and has a phase angle equal to the load power factor angle. It is not resistive or capacitive as resistors and capacitors do not provide the necessary inductance for voltage measurement.
