a battery of 6V and internal resistance 0.5 ohm is joined in parallel with another of 10V and internal resistance 1 ohm. the combination sends a current through an external resistance of 12 ohm .find thr current through each battery

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
