amplifiers operated with Common emmitter configuration for bipolar transistors ,
will give both voltage & current gain .
Though equivalent fet & mosfet circuit topologies exist , these amplifiers operate
more on signal voltage on input & the signal current is negligible compared to a
bipolar transistor.
The breakdown voltage of a diode is the minimum voltage at which it conducts in both directions. If you have a 100-volt rectifier diode (1N4002) and you wire it into a 110v circuit, it will flow current in both directions and you'll get no rectification.
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
The rating is about 1500W. This is for both the input and the output. Output voltage is usually 2,000 volts. Divide watts by input volts to get input current. And divide watts by output voltage to get output current. -Joe
It doesn't matter as long as you measure both voltage and current in same units.
Tis question is incompleet.1000 va =1 kva.This is the power capacity of transformer. A transformer having 2 currents Primary current and secondary current . for that we required both voltage. Simply we can calculate by a formula Voltage x Current x 0.8(power factor)=1000.
high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib
Yes. Most microprocessor based relays that have both voltage and current inputs can provide overcurrent and over voltage protection simultaneously. Short circuit current is the same as overcurrent.
Power is contituted by both current and voltage So we consume both current and voltage
You get power, which is voltage * current (so both!).
CC gives only current gain, but no voltage gain; gives only limited power gainCB gives only voltage gain, but no current gain; gives only limited power gainCE gives both voltage and current gain; gives large power gain
By Ohm's Law, current is voltage divided by resistance, so if you double both the voltage and the resistance, the current would remain the same.
a. the current and voltage in phase
Current = voltage x resistance. Therefore the current will be the same, assuming both frequencies are the same input voltage.
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.

A resistor drops both voltage and current, however the term "drop" is generally used to indicate a voltage or current drop across the device, so it is more correctly stated that a resistor drops voltage, by allowing the current in the circuit to decrease.
It is impossible to separate the two. The voltage determines the magnitude of the current, and the current causes the damage. So, they are both responsible for electric shock.
