A rheostat is connected in series with a load to allow for the adjustment of current flowing through the load. By changing the resistance of the rheostat, the voltage across and the current through the load can be controlled, enabling fine-tuning of the load's performance. This configuration ensures that the entire current passing through the load also passes through the rheostat, allowing for effective regulation of power delivered to the load.

How current coil is connected in energy meter?
It's connected in series with the load.
When to use a rheostat?
Depending on the situation. The purpose of the rheostat is use to change the resistance of the circuit. The rheostat is use to define Ohm Laws the 2nd situation is use to find out what the fixed resistor's resistance. 3rd purpose : used to control the resistance of circuit. eg Radio
Which circuit the ammeter connected in parallel?
An ammeter is always connected in series and a vlotmeter in parallel
What motor must be never run without a load connected to them?
DC Series motor should never run without load connected to it because starting torque for DC series motor is infinite and running it on no load will damage the motor due to overspeeding.
How is ammeter and voltmeter attached to a circuit?
Ammeters are connected in series with the load under test. This requires the load be disconnected from the source, and the ammeter placed in circuit. Voltmeters are connected in parallel with the load under test. This does not require any circuit changes. Sorry, but WikiAnswers does not support illustrations.
What is the function of rheostat in this experiment?
A rheostat is the name given to a variable resistor when it is used to control current. When a variable resistor is used to control voltage, we call it a potentiometer.A rheostat is connected in series with a load, and two of its three terminals are used. A potentiometer is connected in parallel with the supply, and each of its three terminals are used.So the terms 'rheostat' and 'potentiometer' are the names given to describe the function of a variable resistor, not the variable resistor itself.
What are the functions of rheostat?
Rheostat is simply a variable resistor. i.e., typically 3 contacts, either end of resistive element and slider contact that moves along resistive element. So, in old radios would typically be used as a volume control.AnswerA variable resistor may be used to control current, in which case it is called a rheostat. Or it may be used to control voltage, in which case it is called a potentiometer. In other words, the terms 'rheostat' and 'potentiometer' do not describe devices but, rather, they describe two applications of a variable resistor.As a rheostat, the variable resistor is connected in series with a load, and two of its three terminals are used -one of the fixed terminal and the slider terminal.As a potentiometer, the variable resistor is connected in parallel with a load, and each of its terminals are used. The two fixed terminals are connected across the supply, and one of the fixed terminals, together with the slider terminal, is connected across the load.
How ammeter connected?
In series with a load.
What terminals of a rheostat do you connect to?
A rheostat typically has three terminals: two are connected to the resistor element, and the third is the wiper that moves along the resistive track. To use a rheostat, connect one of the outer terminals to the power source and the other outer terminal to the load. The wiper terminal can then be connected to adjust the resistance in the circuit, allowing for control over the current flow.

What happens when a voltmeter is connected in series with load?
when we connected voltmeter in series it takes large current and voltage and the resistance is considerably decreases.this is why we had connected voltmeter in series combination.
Which circuit the ammeter connected in parallel?
An ammeter is always connected in series and a vlotmeter in parallel
What is the purpose of a resistor connected in the series with the load resistor?
Divide the voltage
Why is ammeter connected in series with the load?
An ammeter is connected in series with the load to measure the current flowing through the load. By placing the ammeter in series, it becomes a part of the circuit path so that all the current flowing through the load also passes through the ammeter, allowing for an accurate measurement of the current.
What motor must be never run without a load connected to them?
DC Series motor should never run without load connected to it because starting torque for DC series motor is infinite and running it on no load will damage the motor due to overspeeding.
What happens if you energize power to wire on n.c. contacts?
If the relay contacts are in series with a connected load, then the load will energize.
