What phase current is flowing in a balanced purely resistive 480V 3 Phase Delta connnected system with a demand of 96KW?
96 kW means 32 kW from each phase. If the load is star connected each resistor has 277 volts across it and carries 32,000/277 amps, 115.5 amps. The load resistors are 277/115.5 ohms or 2.40 ohms
If the load is delta connected each resistor has 480 volts across it and carries 66.7 amps. The load resistors are 480/66.7 ohms or 7.20 ohms.
In both cases the line current is 115.5 amps.

How an analog volt meter works?
The meter movement has a current flowing through a coil. That coil is on a magnet. The electromagnet with the needle moves according to the current flow. That flow is established by resistive ladders inside the meter.
Is a wattmeter required to measure the active power delivered to a resistive load?
No. If the load is truly resistive, just measure the voltage across the load (in volts)and the current flowing in it (in amps) and multiply them. eg: 115 volts at 1.5 amps = 172.5 watts.
Why was the capacitor discharging current negative?
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
On what factors the current flowing through a device depends?
Current flowing through a device depends on resistance offered by that device.
What does it mean to source current?
the source current is the current that flows from the power source.

What is the Ammount of current flowing?
The measurement of how fast the current is flowing is the Ampere.
What is the name of flowing electricity?
Flowing electricity is called electric current.
Why resistor do not have positive or negative terminal?
cuz a resistor is basically a long wire , that resists some of the charges flowing across it. it has resistive properties which stops some of the current from flowing from one terminal to the other. so....as it is just a piece of wire....it doesn't need a +ve or a -ve terminal
What is unwanted heat loss called in electricity?
Unwanted heat loss in electricity is called resistive loss or I2R loss, where I represents the current flowing through a device and R represents the resistance of the device. This type of energy loss occurs as heat when electrical current passes through a conductor with resistance.
What does a inductive ammeter do?
It measures current by creating a coil around the current carrying wire. Current flowing in the wire induces a current in the amp-meter proportional to the current flowing in the wire.
Why was the capacitor discharging current negative?
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery.

Current flowing through a device depends on resistance offered by that device.
When charges continually shift from flowing in one direction to flowing in the reverse direction there is a what current?
Alternating current would fit this description.
In a solenoid, will there be a magnetic field if there is no current flowing through it?
Yes, a solenoid will still have a magnetic field even if there is no current flowing through it.
How can you tell electric current current is flowing in the circuit?
You can measure current - or the lack of current - with an ammeter.
