The current strength in the conductor is 2 Amperes. How much should the current strength be increased so that the same electric charge passes through the cross-section of the conductor in a time interval 3 r less?

I1 = 2 A.

t2 = t1 / 3.

Q1 = Q2.

I2 -?

The strength of the current I in the conductor is determined by the formula I = Q / t and shows what electric charge Q is transferred through the cross section of the conductor during time t.

I1 = Q1 / t1.

Let us express the electric charge that passes through the cross-section of the conductor Q1 = I1 * t1.

I2 = Q2 / t2.

Since Q1 = Q2 and t2 = t1 / 3, then I2 = 3 * Q1 / t1 = 3 * I1 * t1 / t1 = 3 * I1.

I2 = 3 * 2 A = 6 A.

Answer: the current strength should be 3 times higher than the initial one and be I2 = 6 A.
