Construction of UJT
The fundamental structure of a UJT is illustrated in fig. (a). It comprises an n-type silicon bar that is lightly doped. Two end connections are taken from bar known as base-one (B1) and base-two (B2). A heavily doped p-type region is diffused to n type nearer to B2. This creates a pn junction with the bar as illustrated in fig.(a). A lead is connected to p region called emitter (E). Schematic symbol of UJT is demonstrated in fig. (b).
A cue ball has a mass of 0.160 kg is at rest on a frictionless pool table. The ball is hit dead center by a pool stick which applies an impulse of +1.40 Ns to the ball. He ball the
It is based on the photovoltaic effect. One of the semiconductor regions is made so thin that the light incident on it reaches the p-n junction and gets absorbed. It changes solar

Q. Find the effectual resistance between A and B. 1/R p = 1/R 1 + 1/R 2 R p = R 1 R 2 / (R 1 + R 2 ) = 15 X15 / 30 = 7.5 ohm
NEWTON ? "The force which forms an acceleration of 1 ms-2 in a mass of 1 kg". It is represented by N.
