1. Given the following circuit: 5 ns D A F 1ons The gate delays are as shown above the gates. A, B, Care three input, and all of them are varying, as given below: A = 0 at time 0, and stays constant until time = 20 ns, when it changes to 1 and stays constant there after B = 1 at time = 0, and stays at 1 value until time = 35 ns, and then changes to 0 at35 ns, and stays constant after that. C= 0 at time 0 and changes to 1 at 50ns Plot A, B, C upto time = 70 ns. LL

Wheatstone Bridge Method

A Wheatstone bridge is a circuit used to measure unknown resistance by measuring the ratios of the two branches of the circuit such that each branch has two resistance and out of four resistance one is unknown. The two branches are joined in between with the help of galvanometer which is used to determine the direction of the current. The main advantage of this circuit is that it can provide the most accurate measurement (different from a simple voltage separator).
