Question

$({6}^{ - 1} \times {7}^{2} \div {6}^{2} {7}^{ - 4} {)}^{7 \div 2}$
​

Answer 1

Explanation:

So if connected in series, a very small current will flow or no current will flow. The reading on the voltmeter will be more or less same as it was initially showing. Since no current flowing, voltmeter will show the voltage of battery connected across. ... But current chooses a path of low resistance in parallel circuit
