Power cords have different voltage rate, example 7A/125V cord can hold much voltage than 3A/125V. The higher the current flow can melt the lower type of power cord that is dangerous and can cause fire. Base on my knowledge there are different types of power cords according to the ampere and voltage needed.
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
answer is actually voltage
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
To sense the current flow across the current transformers and to monitor the current ratings. In current transformers no voltage variations occurs. but in voltage transformers it is mainly used to increase or decrease the voltage value.
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"
There are two types of current AC current DCcurrent
Voltage and current are two different things. Voltage is potential energy per charge, in joules per coulomb, while current is charge transfer rate, in coulombs per second. Its that same as saying that a battery has voltage but no current, because there is no load. Well, a capacitor resists a change in voltage by requiring a current to change the voltage. Once that voltage is achieved, there is infinite resistance to the voltage, and thus no current.
Nothing can change electric current to voltage. You can compare "current " to rate of flow, while "voltage" is the energy level. Transformers can be used to increase or decrease the voltages of alternating current as is done from 'street power' to domestic power.
Yes. While it isn't clear what device you are talking about, and different devices have different characteristic curves (for example, a straight line for a resistor), a voltage is required for a current to flow, so if there is no voltage, there won't be any current, either.
No. They are two different things.
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Alternating Current "AC" & Direct Current "DC"
Current depends on the Wattage and the voltage rating of the device.
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
A parallel circuit has the same voltage but different current in each leg and series circuit has the same current but different voltage on each components unless the same value.
