voltage is directly proportional to resistance, and the current is inversely proportional to resistance. According to Ohm's Law, current is directly proportional to voltage.

What is the relationship between the voltage and the current when the resistance is kept constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
What determines the current in each branch of a parallel circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
How to find resistance?
-- Apply a small, known voltage between the terminals of the device. -- Measure the current through the device with the voltage applied. -- Calculate the resistance of the device. It's (voltage) divided by (current).
What happens to voltage and current in a parallel circuit?
-- The voltage between the ends of each parallel branch is the same. -- The current through each parallel branch is inversely proportional to the resistance of that branch. (It's the voltage divided by the resistance of the branch.)
What is the mathematical relationship between heat dissipation and applied voltage?
Heat dissipation = (applied voltage)2 / total effective resistance of the circuit
Does lowering resistance increase current?
Current is proportionally inverse to resistance and when the voltage is fixed, lowering resistance will increase the current
What happen to the current when the voltage increased if the resistance are constant?
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
What happens when resistance is varied in a circuit?
A resistor will not change its value, unless the voltage exceeds the designed power capacity of the resistor. As the voltage increases, the current will increase, if the current gets too high it will cause the temperature of the resistor to increase, if the temperature exceeds the power rating of the resistor then the resistance WILL change. If it goes too High in temperature the resistor will open and current will no longer flow. A resistor is used to control current, and indirectly the .voltage depending on the application. Hope This helps. You must use Ohms Law to see the relationship.
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.
Define electrical conductivity?
Conductivity is the inverse of resistance. Since Ohm's Law states that current is voltage divided by resistance, it also states that current is voltages times conductivity.
Why there is a relationship between current and voltage?
because current is the ratio of voltage and resistance.
What is Difference between peak inverse voltage and break down voltage?
Two names for practically the same condition. Peak inverse is name whereby the maximum voltage can be sustained. Breakdown is actually the point where a reverse voltage is reached and reverse breakdown has occurred
What causes low voltage to the transmission selonoid?
Cables aren't perfect conductors, they have a bit of resistance. This resistance cacuse a certain voltage drop. But the drop isn't proportional to the voltage running through the cable, so at lower voltages the proportion lost to internal resistance in the cable will be bigger than at higher voltages.

What are the Importance of of peak inverse voltage in rectifier
Explain the relationship between voltage current and resistance?
The ratio of voltage to current is called resistance. In hydraulic terms, you can equate voltage to the difference in pressure between two points, current with the resulting flow of fluid between those points , and resistance as the opposition to that flow.
What is the relationship between the voltage and the current when the resistance is kept constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
What pick inverse voltage?
You mean peak inverse voltage.It is the maximum voltage (peak) the diode can be reversed biased (inverse) by without being destroyed.
