10(a)[2]
V = IR in any form or (R =) V / I
(R = 9.2 / 0.004 =) 2300 Ω
10(b)[4]
(much) greater current in lamp OR lamp activated / lights / glows / gets brighter owtte
resistance of thermistor / component / K reduced (compared to value at (very) low temperature)
voltage / p.d. of point X / across R increases
(larger) current in lamp
10(c)[1]
thermistor
