What happens to the current when the voltage is doubled and the resistance is constant?

If the voltage is doubled and the resistance is constant, Ohm's Law states that the current will also double. This is because the relationship between voltage, current, and resistance is linear, and increasing the voltage will directly increase the current flow.


What will happen to the current if double the length of the wire?

If you double the length of the wire while keeping the resistance constant, the current will halve because resistance is directly proportional to the length of the wire. This is described by Ohm's law (V = I * R), where V is voltage, I is current, and R is resistance.


A 4 ohm resistance wire is doubled on it calculate the new resistance of the wire?

The resistance of a wire is directly proportional to its length, so doubling the length will also double the resistance. Therefore, doubling the 4 ohm resistance wire will result in a new resistance of 8 ohms.


26 How do you position the test equipment into the circuits ensuring the correct polarity?

When positioning test equipment into circuits, always refer to the user manual for specific instructions. Typically, ensure that the positive probe of the equipment is connected to the positive terminal of the circuit/component and the negative probe to the negative terminal, respecting proper polarity. Double-check connections and use appropriate safety measures to prevent damage or injury.


A lenght of cirular wire as a resistance of 1 ohms if its the diameter was double its resistance woul be.?

If the diameter of the circular wire is doubled, the resistance will decrease by a factor of four, resulting in a resistance of 0.25 ohms. Resistance is inversely proportional to the cross-sectional area of the wire, which is affected by the diameter.

Why the wires in the resistance box are double folded?

The wires in the resistance box are double folded to reduce their resistance value by a factor of 4, as resistance is inversely proportional to the cross-sectional area of the wire. This allows for more precise resistance increments to be achieved by varying the length of wire exposed in the circuit.


What is the value of the resistance when both length and diameter are double?

Doubling the diameter of a circular-section conductor will quadruple its cross-sectional area and, therefore, reduce its resistance by a quarter. Doubling the length of a conductor will double its resistance. So, in this example, the resistance of the conductor will halve.


What can you say about the sum of two positive integers?

The sum will be a positive integer.It will be at least as large as double the smaller integer and at most as large as double the larger integer.


What are the two reasons for the current to double in a circuit?

Since current = voltage / resistance, I = V/R, the current in a circuit will double if either the voltage doubles, or the resistance is halved.

If you double both the voltage and the resistance in a circuit what would be the effect on the current?

If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.

What happens to the resistance as the area increases?

Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.


Which is a better conductor between a short wire and long wire?

Double the length is double the resistance. Resistance of a wire is the resistivity of the material, times the length, divided by the cross-section area.
