What else can I help you with?
What device increases or decreases the volt- age of alternating current?
A transformer can step up or step down AC voltage
How does loading effect affect flow of current?
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
A device that increases the voltage of an alternating current is called?
That's called a transformer.
What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
An electrical tool that increases or decreases the voltage in an electrical current is?
capacitors
Does electrical current generally increase as resistance decreases?
Ohm's Law Voltage = Current x Resistance. So for a fixed voltage as R decreases then current increases proportionally.
How are current and voltage related are they directly proprtional or inversely proportional?
Current and voltage are directly proportional according to Ohm's Law. This means that as voltage increases, current increases proportionally, and as voltage decreases, current decreases proportionally. Mathematically, this relationship is expressed as I = V/R, where I is current, V is voltage, and R is resistance.
When resistance decreases what happens to current?
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
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.
Which law says voltage increases current decreases?
Ohm's law says the opposite.
Is voltage directly or inversely proportional?
Voltage is directly proportional to current, meaning that as voltage increases, current also increases and vice versa, as per Ohm's Law. However, voltage is inversely proportional to resistance, meaning that as voltage increases, resistance decreases and vice versa.
What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
