Just trying to answer a few questions that a can't find the answers for.
If ther is a resistive load we got curent and voltage in phase. If the load is inductive curent lags behind the voltage. IN THIS CASE THER IS BOTH LOAD THAT MEANS CURENT WILL LAG BEHIND THE VOLTAGE
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
In what sense.
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance

If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
Nothing will happen to the resistance of the circuit. However, with the switch open, it will be 'seen' as having infinite resistance from the supply side.
If the inductance in an RLC circuit were larger, the phase angle between the voltage and current would increase, leading to a greater lag of the current relative to the voltage. This occurs because higher inductance increases the reactance of the inductor, causing the circuit to behave more like an inductor and less like a resistive load. Consequently, the overall impedance becomes more inductive, resulting in a larger phase angle.
If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.
If it is connected in series with a circuit then it might raise the resistance too high and fail the system. Parallel connection is a circuit is probably the best bet you have.
The purpose of a voltmeter is to indicate the potential difference between two points in a circuit.When a voltmeter is connected across a circuit, it shunts the circuit. If the voltmeter has a low resistance,it will draw a substantial amount of current. This action lowers the effective resistance of the circuit andchanges the voltage reading.
In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.
