How would i calculate the specific heat capacity using a temperature-time graph
Assuming that you know the mass and the heat input, you can. What formula can you write for the heat energy required to raise the temperate of a mass by a given amount? The rate of change of temperature () is the gradient of your graph.

i only know the mass, temperature, time, current and voltage

You can multiply the current and voltage to get power and then multiply by the time to get the energy. Then use the SHC equation to work out the SHC.

can i use I t V/m∆θ = c

why do you need to divide by time to get J
I meant multiply, just changed it, sorry.
