Question:medium
Find the terminal voltage of a cell having emf \(12\,V\), internal resistance \(1\,\Omega\), and external resistance \(5\,\Omega\).
Find the terminal voltage of a cell having emf \(12\,V\), internal resistance \(1\,\Omega\), and external resistance \(5\,\Omega\).
Show Hint
Terminal voltage while delivering current is
\[
V=E-Ir.
\]
If the cell is not supplying current, terminal voltage equals emf.

- A particle of charge \( q \) is moving with a velocity \( \vec{v} \) at a distance \( d \) from a long straight wire carrying a current \( I \) as shown in the figure. At this instant, it is subjected to a uniform electric field \( \vec{E} \) such that the particle keeps moving undeviated. In terms of unit vectors \( \hat{i}, \hat{j}, \) and \( \hat{k} \), find:
the magnetic field \( \vec{B} \),
the magnetic force \( \vec{F}_m \), and
the electric field \( \vec{E} \) acting on the charge.
