On a 230 V supply it settles to a steady current of Two cells, each of emf 1.5 V and internal resistance 0.5 Ω, are connected in series across a 2 Ω resistor. TheTwo identical cells, each of emf 1.5 V and internal resistance 0.5 Ω, are connected in parallel across a 1 Ω rThe maximum current that can be drawn from a cell of emf 1.5 V and internal resistance 0.3 Ω is:Power loss in transmission cables of resistance Rc delivering power P at voltage V is P²Rc/V². To minimise thiAt a junction, currents of 3 A and 5 A flow in, and 2 A flows out through one branch. By Kirchhoff's junction A Wheatstone bridge is balanced with arms P = 10 Ω, Q = 20 Ω and R = 15 Ω. The unknown resistance S is:A 3 Ω resistor is connected in series with a parallel combination of a 6 Ω and a 3 Ω resistor. The equivalent When the temperature of a metallic conductor rises, its resistivity increases mainly because:A galvanometer of resistance G can be converted into a voltmeter of range V by connecting in series a high resTwo 100-W bulbs are connected in series across 220 V.
