If the voltage (V) were plotted (vertically) on the same graph versus current (I) for two ohmic conductors with different resistances, how could you tell which is less resistive?
Answer to relevant Questions(a) Three 1.5-V batteries are connected in series. What is the total voltage of the combination? (b) What would be the total voltage if the cells were connected in parallel? In a proton linear accelerator, a 9.5-mA proton current hits a target. (a) How many protons hit the target each second? (b) How much energy is delivered to the target each second if each proton has a kinetic energy of 20 ...A material is formed into a long rod with a square cross-section 0.50 cm on each side. When a 100-V voltage is applied across a 20-m length of the rod, a 5.0-A current is carried. (a) What is the resistivity of the ...Two 6.0-V batteries and one 12-V battery are connected in series. (a) What is the voltage across the whole arrangement? (b) What arrangement of these three batteries would give a total voltage of 12 V? Show that the quantity volts squared per ohm (V2/Ω)has SI units of power.
