Power is measured in watts (W), which is energy per unit time (Joules per second).
\[Energy \;(in \;Joules) = Power \;(in \;Watts) × Time \;(in \;seconds)\]Therefore, \(\text{6 watt × second = 6 Joule.}\)
In the Wheatstone bridge shown below, the sensitivity of the bridge in terms of change in balancing voltage \( E \) for unit change in the resistance \( R \), in V/Ω, is __________ (round off to two decimal places).

An ideal low pass filter has frequency response given by \[ H(j\omega) = \begin{cases} 1, & |\omega| \leq 200\pi \\ 0, & \text{otherwise} \end{cases} \] Let \( h(t) \) be its time domain representation. Then h(0) = _________ (round off to the nearest integer).
