Answer:an open flame
Explanation:
Flammable materials like alcohol should never be dispensed or used near an open flame
Answer:
720 V
Explanation:
Given that,
The number of turns in primary coil, N₁ = 60
The number of turns in secondary coil, N₂ = 360
The input rms voltage, V₁ = 120 V
We need to find the output rms voltage of the secondary coil
. The relation between number of turns in primary coil - secondary coil to the input rms voltage to the output rms voltage is given by :
<h3>So, the output rms voltage of the secondary coil is 720 V. Hence, the correct option is (b).</h3>
