## What is double wire?

Double wire is a continuous metal wire that is formed into pairs of loops that are connected together to make up a binding element. The loops resemble a letter C when open and viewed from the end. After the pages are loaded onto the element, the wire is closed into a circular shape.

## When the wire is double on its own?

Solution : On doubling the metallic wire on itself, the length of wire becomes half `(i.e., I_2 = 1/2l_1)` and area of cross section gets doubled (ie, `a_2=2a_1)` From relation `R=(rhol)/a,(R_2)/(R_1)=l_2/l_1xxa_1/a_2=1/2xx1/2=1/4or R_2=1/4R_1` Thus the resistance becomes one-fourth.

**What is the meaning of a wire is doubled on itself?**

wire is doubled on itself means that it has now folded to make its length half and cross section area double. that L=l/2. A=2a.

**How long is wire doubled on itself?**

Resistance of a wire is directly proportional to the length of the wire. As its length increases it’s resistance increases. If it is doubled again, the length of the wire becomes 4L and it’s resistance becomes 4x.

### When the length of a wire is doubled its resistance becomes?

From the equation, we understand that resistance is directly proportional to the length of the conductor and inversely proportional to the crossectional area of the conductor. Doubling the length doubles the resistance.

### When length of wire is doubled What is the change in resistance?

Let the original length of the wire be l and the original resistance be R . Also, let A be its cross sectional area. So, the new resistance, after doubling the length of the wire, becomes twice of the original resistance. Hence, if the length of a wire is doubled, then its resistance becomes doubled.

**What happens when a wire is doubled on itself?**

When the wire is doubled on itself, its length becomes halved (L/2) and area of cross-section becomes doubled (2 A).

**What is the meaning of doubled on itself?**

wire is doubled on itself means that it has now folded to make its length half and cross section area double. that L=l/2.

#### What will happen on resistance if wire is doubled?

So, the new resistance, after doubling the length of the wire, becomes twice of the original resistance. Hence, if the length of a wire is doubled, then its resistance becomes doubled.

#### When wire is doubled What is the diameter?

Detailed Solution Calculation: Resistance is inversely proportional to the cross-sectional area. If, the diameter becomes double, the area increases by the square of diameter i.e. 4 times; Therefore, resistance becomes 1/4 times.

**What happens when resistance is doubled?**

if resistance is doubled then the current would be halved as resistance is inversely proportional to the current flowing in a circuit. that is if the resistance is doubled the current would be halved.

**Can you put 2 black wires together?**

This is the typical way to connect a switch. The 2 blacks connected are “power in, power out” to the next switch in the circuit. The pig-tail to the dimmer connected to the two blacks is also typical.
