A small amount of phosphorus is added to silicon so that there are 2.5 × 10 17 conduction electrons per cubic meter and 9.0 × 10 14 holes per cubic meter. Let µ e = 0.13 m 2 /V.s and µ h = 0.05 m 2 /V.s. The resistivity in Ω - m will be When a capacitor was connected to the terminal of ohmmeter, the pointer indicated a low resistance initially and then slowly came to infinity position. This shows that capacitor is The power in the signal $$s\left( t \right) = 8\cos \left( {20\pi t - {\pi \over 2}} \right) + 4\,\sin \left( {15\pi t} \right)$$ is A 75 ohm transmission line is to be terminated in two resistive loads R 1 and R 2 such that the standing patterns in the two cases have the same SWR. To obtain the desired result, the values of R 1 and R 2 (in ohms) should be Each machine cycle of 8051 corresponds to
