Advanced Physics for You has been carefully designed to be inviting, interesting and motivating to the student, with features that make it highly supportive of individual learning. It fully covers the new AS-Level and core topics of all A2 specifications.Solving circuit problems Take care when solving circuit problems using the equation V = I X R. Be clear whether the values you put ... Example 6 A 12 volt car battery is recharged by passing a current through it in the reverse direction using a 14 V charger. Calculate the charging current. Note that the 12 V e.m.f. opposes the 14 V e.m.f., so: the sum of the e.m.f.s = 14V + -12V = 2V There are two internalanbsp;...
