In circuit a the battery that supplies energy has twice as much voltage as the battery in circuit
b. however, the current in circuit a is only one-half the current in circuit
b. circuit a presents ____________ the resistance to the current that circuit b does.
More resistance. This is because V=IR. Circuit A has more voltage V but less current I. So R must be larger in A. In fact the resistance R in circuit A is 4 times as large as the R in circuit B.
