What is electrical induction?
'Induction' describes the process by which a varying current in one conductor 'induces' a voltage into either the same conductor ('self induction') or into a nearby conductor ('mutual induction'). Mutual induction is the process by which a transformer works.
What is the fuction of the step-up transformer?
Step-Up Transformers increase the primary voltage to a higher voltage, of same frequency.
Why does higher applied voltage with the same resistance results in more current?
Ohm's law: Voltage = Amperes times Resistance. This means that increasing voltage while keeping resistance the same must result in an increase of current.
What is V-I characteristics of zener diode?
Work in reverse bias.(breakdown at a particular voltage to keep the volt. constant so used as voltage regulator) same as diode when forward biased.
How you increase current by keeping voltage constant?
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.

Why is induction more pronounced in coils?
More wire in a smaller space. Each turn amplifies the induction voltage in the same way a string of series connected batteries multiplies voltage.
What is the fuction of the step-up transformer?
Step-Up Transformers increase the primary voltage to a higher voltage, of same frequency.
Why friction and windage loss for an induction motor remain constant with change of stator voltage?
Because the RPM remains same
What increases when current increases?
If current increases, then voltage also has to increase, assuming that resistance stay relatively the same. Power will also increase. Since power is the product of voltage and current, then the power increase would be the square of the voltage or current change.
When you stepup ac voltage the current drops.What will happen with CURRENT if DC is stepped up?
WHEN YOU STEP UP THE VOLTAGE AND THE LOAD IS THE SAME MORE CURRENT WILL FLOW NOT LESS. AND THAT WILL HOLD TRUE FOR DC AS WELL. IF THE LOAD REMAINS THE SAME AND YOU INCREASE THE CURRENT AC OR DC THE VOLTAGE WILL INCREASE
When a battery runs out does the battery voltage increase decrease or stay the same?
It should decrease
Why does higher applied voltage with the same resistance results in more current?
Ohm's law: Voltage = Amperes times Resistance. This means that increasing voltage while keeping resistance the same must result in an increase of current.
What happens to the electric current in a wire when voltage is increaced?
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
Does transformer doubles the power?
No. Power is constant. Transformers neither increase nor decrease power, except for minor losses. They increase or decrease voltage, and they decrease or increase current, but the product of voltage and current, i.e. power, remains the same.
If the resistance increases what will happen to voltage and current?
If you have a simple circuit. For eg: One voltage source and one resistor, then the voltage of the circuit will always remain the same, the current however will decrease following Ohms' Law V=I*R. If we have a current source instead of a voltage source, we are forcing the current to be a certain value so if we increase the resistor value the current will remain the same but the voltage will increase.
Why does increasing the voltage of a wire have the same effect on the current that decreasing the resistance has?
Ohm's Law is Voltage = Current x Resistance or written v - I x R. So if you raise the voltage and keep R the same current must increase to satisfy the equation. I = V/R. Similarly if you reduce R and keep V the same current will also increase proportionally.
