Resistance is probably the missing word. I = e/R. If R is greater, I is less.

In 3 phase voltage increases and current decreases why?
If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.
What happens when you increase the current to a solenoid?
increasing the voltage increases the current. this is because when you increase the voltage you make the pressure that is pushing on the current (which is making it move) greater, therefore increasing it. <<>> Ohms law states that, the current is directly proportional to the applied (EMF) voltage and inversely proportional to the resistance in a circuit. The formula you are looking for is I = E/R. You supply some figures for Voltage (E) and Resistance (R).
What is the Requirement for transmitting extra high voltage alternating current?
To reduce the losses, like I2r in the conductor and as per transformer principle when voltage is high , current is less. this means less equipment ratings, cost reduction, less line drop, more efficiency, less conductor size
What is internal resistant of a DC source?
An ideal voltage source has zero internal resistance so that the voltage stays constant with any load current. A practical voltage source should have less than 5% voltage drop at the rated load current.
What is the relationship of current and voltage in a resistive circuit?
The current through the circuit is directly proportional to the voltage across the circuit. The proportionality constant is 1/R, where 'R' is the total effective resistance of the circuit. C = V / R V = C R R = V / C
What is the purpose of transmitting electricity at high voltage?
Less current, greater efficiency, reduced volt drop
What is the purpose at transmitting electricity at high voltage?
Less current, greater efficiency, reduced volt drop
Is the mean rectified voltage now greater or less?
Less
What is a Reverse current relay?
A reverse current relay prevents a generator from discharging the battery when generator output is less than battery voltage. When generator output is greater than battery voltage, the reverse current relay closes and connects generator to electrical bus.
Which is greater 1kw equals equals KVA?
In the case of DC, and in AC when current and voltage are in phase, a volt-ampere is the same as a watt (and therefore, a kilo-volt-ampere is the same as a kW). In the case of AC, when current and voltage are NOT in phase, power = voltage x current x power factor; the power factor is the cosine of the angle between current and voltage, and it is always less than or equal to one. In such a case, a kVA would be less than a kW.
Will the current in a light bulb connected to a 200-v source be greater or less than when the same bulb is connected to a 110-v circuit?
It will be greater:current = voltage / resistanceSince the bulb's resistance doesn't change, then current is a direct function of voltage.
What is the effect of changing the voltage?
Less current.
What is a reversing relay?
A reverse current relay prevents a generator from discharging the battery when generator output is less than battery voltage. When generator output is greater than battery voltage, the reverse current relay closes and connects generator to electrical bus.
Is the current greater or less?
Yes.
Does current stay the same when voltage changes with converter?
No. Power stays the same. Power is voltage times current. So, if voltage is doubles, current has be halved, less efficiency losses.
In 3 phase voltage increases and current decreases why?
If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.
