Design a three-channel inverting adder to satisfy the following relation:
Vo = -(10V1-0.5dV2÷dt +2 V3)

In a series LCR circuit with L = 5/3 H, R = 10 Ω and C = 1/30 F and a source of emf
E = 600 V, determine the charge on the capacitor as a function of time. It is given that
the initial charge on the capacitor is zero and the initial current in the circuit is 9A.

Instead of measuring resistance suppose that in (a) data of the variation of
current with the length of wire is collected. Show how such data can be
used to determine the resistivity of the wire

Suppose in an experiment, data is collected of the variation of current with
resistance R. Next a plot of R vs I
-1 is made. How does one determine the
value of V from that graph. (Explain your answer using an appropriate
expression.)
