There are 2 nichrome wires P and Q are connected in series to battery of emf , V .
Both P and Q are of same length bu the diameter of wire P is bigger than that of wire Q . When wire P and Q glow steadily , which one would glow brighter ?
The Attempt at a Solution
What determines the brightness of the nichome wire ? Is it the temperature(as in when its hotter it glows more) ? Then how is different when the nichrome wires are connected in parallel ?
