######
Four relations are given below. Identify the correct relation regarding a transistor?

The emitter current (IE) of a transistor has two components such as base current (IB) and collector current (IC). The base current (IB) is about 2% of the emitter current (IE), but the collector current (Ia) is about 98% of the emitter current (IE).

∴ IE > IC > IB

IE = IB + IC

While estimating domestic wiring cost, if the length of the PVC conduit required is 62 meters, then what is the length of the cable required?

The size of the conduit is 62 meters. In conduit, there is a 2-phase wire and 1 neutral wire. Therefore the total number of conducting wire is 3 in a conduit

Total length of cable = 62 × 3 = 186 meters.

Observe the given table. The truth table represents gate?

In the exclusive OR gate (XOR gate) has two inputs

The ouput will be 1 when either input is 1 i.e X = 1 and Y = 1, but not when both the inputs are 1.

If both the input is zero i.e X = 0 and Y = 0, then the output is 0.
